From a human factors standpoint, you have about 5 seconds before the user gets too frustrated to continue using your product. I did. I'm writing this from my Ubuntu system. Behaviors like this are not exactly motivating me to develop for the Windows 8 platform.

English version

I have to admin that from time to time I have to use Windows too.
Sometimes it works quite good, more often it takes about double the time for your just to fix some silly bug or features. Like this one:

"Switch between apps" won't disappear

aka "switch between apps won't go away",
aka "switch between apps is stupid",
aka "switch between apps is a lie"

Story

This time I was getting stuck at the "Switch between apps"-Popup, that won't go away.
As a very experienced computer user it took be about 10 minutes to figure out how the f*** to get rid of this stupid new feature.

I agree with the writer of this post, that also gave me to the solution of the problem:

Exactly. If I have to spend more time discovering "brand new features" and "modern user interfaces" than I spend time to do my work, I immediately assume that people who use this kind of software or (even worse) write it, are complete retards with no clue about computers. Although also Ubuntu has this "eye candy" (Deutsch: "Klickibunti")-mentality it doesn't distracts the user this much.

This tip was found on this page. I explicitly DO NOT recommend to download the registry keys but to do this by hand. I encourage people to do critical changes in the system (like changing registry keys) always by hand!
